I’m trying to develop a 3D drawing application. Now i can a draw a line using the mouse. While drawing, double click to start the line and another double click to finish the line. So after first double click , i draw the entire scene again and again on mouse move util we click another double click to finish the line. If i have only few no. of line while i draw a new line means its no problem to update the entire scene for every mouse move. But if i have more than 10000 lines means is slow down the drawing speed ?
What my problem is, if anther commands available in opengl to avoid redraw of exist lines while draw a new line ?
